I started reading about oysters to think on this. Turns out they're calling it merroir! Amusing.
In any event,
- the aggregate of surrounding things, conditions, or influences; surroundings; milieu.
- the air, water, minerals, organisms, and all other external factors surrounding and affecting a given organism at any time.
The issue, though, is that terrior is used to mean the qualities in the wine resulting specifically from environmental factors. So perhaps "environmental traits," but there's a reason English speakers are using terroir as well. It's pithy. Environess? Environessence? Stick with terroir, especially if soil has anything to do with it.
